Overall Assessment
This is an interesting specimen of raw, uncut diamond matrix displaying natural crystal morphology. While it lacks the optical performance of a polished gemstone, it holds unique appeal for mineral collectors and educational displays.
Cut Quality
Not Applicable (Rough, uncut crystal specimen)
Brilliance
Subdued due to unpolished and frosted natural faces
Fire
Limited dispersion visible on raw surfaces
Scintillation
Minimal, reflecting natural crystal texture
Proportions
Natural crystal proportions, non-standardized
Symmetry
Natural crystal symmetry with distorted growth faces
Polish
Raw crystal surface, unpolished natural habit
Fluorescence
Cannot be definitively assessed without UV testing, likely Faint to Medium Blue
Inclusions
Cloud clusters, pinpoints, and internal natural mineral inclusions typical of raw diamond rough
Blemishes
Natural surface trigons, rough skin, and minor surface indentation marks
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)
Treatment Detection
None detected; completely natural untreated rough
Estimated Value
Depends on yield potential after cutting; rough mineral value estimated between $300 to $800 USD
Certification Estimate
GIA Rough Diamond Report or Kimberley Process certificate
Investment Potential
Collector/Mineral specimen value rather than investment-grade polished stone
Similar Diamonds
Standard run-of-mine industrial or lower-gem quality octahedral rough diamonds
Setting Suggestions
Raw crystal pendant setting utilizing secure prongs or a protective bezel to showcase natural geology
Care & Maintenance
Store separately to prevent scratching other gemstones; clean with mild soapy water and a soft brush
Interesting Facts
The specimen displays natural crystal growth features such as stepped growth patterns and curved faces typical of unworked diamond crystal forms.
